The Dangers Of Eating Canned Food

The Dangers Of Eating Canned Food. A large amount of food that is found in supermarkets is canned. It would seem that it is very normal and healthy. However, several studies show that this material generates a toxic component that is harmful to your health. Learn about the dangers of eating canned food in the following article.

Can have a special covering made with bisphenol A resins. Remembering the name of this is not important, what you should know is that it accumulates in the body and its effects are not good at all. A study by Harvard University revealed that people that ate canned soup for five consecutive days had a large quantity of bisphenol A in their urine. They then measured the levels for five more days without the consumption of the canned soup and this substance was not found.

Is Bisphenol Toxic?

Bisphenol A (BPA) is studied by many scientists. A publication by the Medical Association Journal indicates that this component is used to produce plastic, resin, and cans. A report done in the United States showed high levels of BPA in babies, children, and fetuses.

Canada was the first country in the world to declare it as a toxic substance. The European Union followed, where they prohibited this product from being used to produce baby bottles. However, BPA resin is still being used in other products, as is the case in the covering of metal cans where food and drinks are placed.

There is still not enough evidence to know the harmful effects of bisphenol A accumulation in the body. Animal testing has shown alarming results. For example, they know that BPA is an endocrine disruptor, which means it can alter the operation of the hormonal system. It is linked to diabetes, cardiovascular diseases, and obesity.

So, the problem is not so much what the cans contain (although you should also pay attention to that), but rather the contact the food has with bisphenol A. Thanks to certain experiments, scientists are doing whatever it takes so that BPA is eliminated from canned products or even so that food in cans that contain BPA is not sold.

Risks of Canned Food

Apart from cans, BPA is found in plastic and vacuum-packaged food. The only packaging or containers that “are saved from it” are glass or paper (have you thought about how the taste of food changes according to how it’s packaged?).

Synthetic chemical products that are used to package, store and process food are silent enemies. Nobody knows what they are consuming and what it can do to your health (or your family’s health). The majority of these components don’t do anything, which is why it can be filtered in food with no problem.

People that eat a lot of canned food are more susceptible to being exposed to these substances that, as we mentioned before, cause obesity, hormonal changes, cardiac problems, and diabetes.

The truth is that there is not a lot that is known about this or about the crucial stages of the body. What is confirmed is that can contain “popular” toxic substances like formaldehyde, known among scientists as carcinogenic. It is also found in plastic bottles (in lesser quantities).

The Danger of Tuna Cans

There is no doubt that canned tuna is one of the most consumed foods because you don’t have to cook it and you can add it to any recipe. The benefits of fish (which contain Omega 3 fatty acids and phosphorus) are left behind because of the mercury that the cans contain.

Mercury is a metal with toxic effects that harm the nervous system. Apart from being present in cans, in some areas where they fish for certain species of fish, the water also contains it. It can increase your risk of suffering from heart attacks, neurosensory changes, interferences in neurological development (in the case of fetuses), etc.

The Risk of Aluminum Can Covering

The majority of cans that are used to store food and are sold in supermarkets have a plastic packaging, also known as epoxide resin that is applied on the outside. This procedure is done to prevent foods from reacting and their acids from eroding the material. The idea is for cans to last a long time, which is why they have a circular form and they put this covering on.

Can Poisoning, an “Old” Problem

If you think that the canned food problem is new, you should learn about the story of John Franklin’s fateful expedition to the Arctic, where many members of the ship’s crew died from eating canned food. They found this out many years later from different studies. The cause was lead poisoning, which they used to seal the cans for conservation. Although this story may be a myth and the procedures of storing food have changed, it’s good to know that the problem with canned food is not new.


The reality is that your can of pinto beans, tuna or vegetable juice could put your health at risk. 17% of the American diet comes from canned food, is it worth it to contaminate your daily grains, protein or vegetables with aluminum and BPA? FDA has approved aluminum food packaging but as explained there is a health risk associated with canned food.

What should you do?

Completely eliminate canned foods and if you are looking for your favorite tomato sauce use the ones in glass jars. Don’t consume vegetables or grains in cans, simply buy fresh ones. The risk of developing many chronic diseases such as cancer, heart disease, obesity, diabetes, nervous system disorder and Alzheimer’s goes down by consuming fresh foods that do not have any packaging.
